20 Sleeping bag. A sleeping bag 20 of the present invention may be of any size and shape. Exemplary shapes include a rectangle, square, “mummy” shape or conical shape. The sleeping bags 20 shown in the drawings herein are in their flapped over position, where a person can insert himself between the upper and lower sleeping bag 20 layers. The foot end of the sleeping bag is where the user's feet go, and the head end of the sleeping bag is where the head of the user goes. The “foot end” of the sleeping bag 20 is the end of the sleeping bag where the user's feet is located. Usually, the foot end can be completely zippered up. The “head end” of the sleeping bag is at the other end of the sleeping bag that is closer to where the user's head usually rests. The head end of the sleeping bag usually cannot be zipped up.

30 Supplement sheet. A supplement sheet 30 of the present invention may be of any size and shape. Exemplary shapes include a rectangle, square, “mummy” shape or conical shape. In some embodiments, the supplement sheet 30 is the same shape as that of the sleeping bag 20, e.g., both are rectangles. In some embodiments, the shape of the supplement sheet 30 is different from that of the sleeping bag 20. Further, a supplement sheet 30 of the present invention may have various physical qualities. In some embodiments, a supplement sheet 30 has a thermo retention capability that is lower than that of the sleeping bag 20. For example, the supplement sheet could be made out of satin, cotton, silk, light weight flannel, nylon or any other synthetic or natural fabric. In some embodiments, a supplement sheet 30 has a thermo retention capability that is the same as that of the sleeping bag 20. For example, the supplement sheet 30 may be made from the same material as that of the sleeping bag. In some embodiments, a supplement sheet has a thermo retention capability that is higher than that of the sleeping bag 20. The size of the supplement sheet of the present invention can be smaller, same as or larger than that of the sleeping bag 20.

31 Water proof supplement sheet. Water proof supplement sheet 31 can be constructed from any material which is substantially water proof. Non-limiting examples include nylon, plastic, parachute material, and any other water resistant fabric. The size of the water proof supplement sheet of the present invention can be smaller, same as or larger than that of the sleeping bag. A supplement sheet 30 of the present invention may be of any size and shape. Exemplary shapes include a rectangle, square, “mummy” shape or conical shape. In some embodiments, the water proof supplement sheet 3 is the same shape as that of the sleeping bag 20, e.g., both are rectangles. In some embodiments, the shape of the water proof supplement sheet 31 is different from that of the sleeping bag 20

40 Attachment means. An attachment means may be any means by which one component of the present invention can be attached to itself and/or another component. Non-limiting examples of attachment means include VELCRO®, buttons, zippers, threads, strings, hooks and glue. VELCRO® is a brand name of fabric hook-and-loop fasteners used for connecting objects. Hook and loop fasteners consist of two layers: a “hook” side, which is a piece of fabric covered with tiny plastic hooks, and a “loop” side, which is covered with even smaller and “hairier” plastic loops. There are many variations to this which include hooks on both sides, for example. When the two sides are pressed together, the hooks catch in the loops and hold the pieces together. When the layers are separated, the strips make a characteristic ripping sound. This creates some disadvantages to the use of velcro in various occasions. VELCRO® is patented in U.S. Pat. No. 2,717,437, the disclosure of which is incorporated in its entirety herein by reference.

50 Pouch for sheets. The pouch for sheets 50 is a pouch where supplement sheets 30 and/or water proof supplement sheets 31 may be stored.

60 Pillow

70 Storage bag. A storage bag 70 can be used to store the sleeping bag.

72 Strap. The strap may be constructed from leather, nylon or cloth.

80 Accessory pouch. An accessory pouch 80 can be used to store undergarments, swim suits, tooth brush, comb, etc. The accessory pouch can be sealed by an attachment means.

Any feature or combination of features described herein are included within the scope of the present invention provided that the features included in any such combination are not mutually inconsistent as will be apparent from the context, this specification, and the knowledge of one of ordinary skill in the art. Additional advantages and aspects of the present invention are apparent in the following detailed description and claims.
